The PRO is the one to ask about if the terminal has to last. It is the only portable in the Castles range certified to PCI PTS 7.x rather than 6.x, and that certification is what decides how many years a device can stay in the field before it has to come out.
The hardware matches: an A73 octa-core at 2.4GHz, 4GB of RAM rising to 8GB, 32GB of flash, a 6.745-inch HD+ display and a 5MP rear camera with 13MP optional. A professional barcode scanner is available.
It is 192 x 81 x 54mm and 436g, on a 3350mAh battery, with a 90mm/sec printer.
What it costs
The rate you pay is negotiated on your volume and card mix, not set by the terminal — two businesses on the same S1F4 PRO can be paying very different money. Find out what yours should be.
